Include the recommended packages

Azure Maps Libraries require a TokenCredential implementation for authentication and an HttpClient implementation for HTTP client.

Azure Identity package and Azure Core Netty HTTP package provide the default implementation.

Authentication

By default, Azure Active Directory token authentication depends on correct configure of following environment variables.

• AZURE_CLIENT_ID for Azure client ID.
• AZURE_TENANT_ID for Azure tenant ID.
• AZURE_CLIENT_SECRET or AZURE_CLIENT_CERTIFICATE_PATH for client secret or client certificate.

In addition, Azure subscription ID can be configured via environment variable AZURE_SUBSCRIPTION_ID.

With above configuration, azure client can be authenticated by following code:

// Authenticates using Azure AD building a default credential
// This will look for AZURE_CLIENT_ID, AZURE_TENANT_ID, and AZURE_CLIENT_SECRET env variables
DefaultAzureCredential tokenCredential = new DefaultAzureCredentialBuilder().build();

// Creates a builder
TrafficClientBuilder builder = new TrafficClientBuilder();
builder.credential(tokenCredential);
builder.trafficClientId(System.getenv("MAPS_CLIENT_ID"));
builder.httpLogOptions(new HttpLogOptions().setLogLevel(HttpLogDetailLevel.BODY_AND_HEADERS));

// Builds a client
TrafficClient client = builder.buildClient();

The sample code assumes global Azure. Please change AzureEnvironment.AZURE variable if otherwise.

See Authentication for more options.

Key concepts

Examples

Get Traffic Flow Segment

System.out.println("Get Traffic Flow Segment:");

// options
client.getTrafficFlowSegment(
    new TrafficFlowSegmentOptions()
        .setTrafficFlowSegmentStyle(TrafficFlowSegmentStyle.ABSOLUTE).setZoom(10)
        .setCoordinates(new GeoPosition(4.84239, 52.41072)));

// complete
client.getTrafficFlowSegment(
    new TrafficFlowSegmentOptions()
        .setTrafficFlowSegmentStyle(TrafficFlowSegmentStyle.ABSOLUTE).setZoom(10)
        .setCoordinates(new GeoPosition(4.84239, 52.41072)).setOpenLr(false)
        .setThickness(2).setUnit(SpeedUnit.MPH));

Get Traffic Flow Tile

System.out.println("Get Traffic Flow Tile:");

// options
client.getTrafficFlowTile(
    new TrafficFlowTileOptions()
        .setTrafficFlowTileStyle(TrafficFlowTileStyle.RELATIVE_DELAY).setFormat(TileFormat.PNG).setZoom(10));

// complete

    new TrafficIncidentDetailOptions()
        .setBoundingBox(new GeoBoundingBox(45, 45, 45, 45)).setBoundingZoom(11)
        .setIncidentDetailStyle(IncidentDetailStyle.S3).setBoundingZoom(11)
        .setTrafficmodelId("1335294634919").setLanguage("en")
        .setProjectionStandard(ProjectionStandard.EPSG900913).setIncidentGeometryType(IncidentGeometryType.ORIGINAL)
        .setExpandCluster(false).setOriginalPosition(false));

Get Traffic Incident Tile

System.out.println("Get Traffic Incident Tile:");

// options
client.getTrafficIncidentTile(
    new TrafficIncidentTileOptions()
        .setFormat(TileFormat.PNG).setTrafficIncidentTileStyle(TrafficIncidentTileStyle.S3)
        .setZoom(10));

        .setZoom(10).setTileIndex(new TileIndex().setX(175).setY(408)));

Get Traffic Incident Viewport

System.out.println("Get Traffic Incident Tile:");

// options
client.getTrafficIncidentViewport(
    new TrafficIncidentViewportOptions()
        .setBoundingBox(new GeoBoundingBox(45, 45, 45, 45))
        .setBoundingZoom(2).setOverview(new GeoBoundingBox(45, 45, 45, 45))
        .setOverviewZoom(2));

// complete
client.getTrafficIncidentViewport(
    new TrafficIncidentViewportOptions()
        .setBoundingBox(new GeoBoundingBox(45, 45, 45, 45))
        .setBoundingZoom(2).setOverview(new GeoBoundingBox(45, 45, 45, 45))
        .setOverviewZoom(2).setCopyright(true));

Troubleshooting

When you interact with the Azure Maps Services, errors returned by the Maps service correspond to the same HTTP status codes returned for REST API requests.

For example, if you search with an invalid coordinate, a error is returned, indicating 400 - Bad Request
